Multi wavelength comprehensive

Wavelength calculation allows people who are learning wavelength physics knowledge to quickly calculate.
In physics, wavelength (λ) is usually defined as the relationship between the periodicity and frequency of a wave, where the wavelength is equal to the distance traveled by the wave within one cycle. The formula for calculating wavelength can be used to measure the characteristics of waves, with the formula λ=c/f, where λ represents wavelength, c represents the speed of light or sound, and f represents the frequency of the wave.
